You are required to answer the following questions, based on the results above: 1. How many observations were used for the regression? 2. How many parameters were estimated in this regression? 3. What is the Explained Sum of Squares (ESS) in the regression? 4. What is the Residual Sum of Squares (RSS) in the regression? 5. What is the Total Sum of Squares (TSS) from the regression? 6. How was the F-Statistic obtained? 7. Interpret the Adjusted R-Squared of the regression. 8. Test the Null Hypothesis that the regression line is not a good fit, against the alternative hypothesis that the line is a good fit. 9. Test the hypothesis that each of the parameters estimated is not statistically significant, against the alternative hypothesis that it is statistically significant 10. IF CGPA2020_Al increases by 1 point, by how much will SGPA2020_A2, increase on average? 11. Was there any difference in performance in the online exams between male and female students? If so, what is the difference? 12. What is the meaning of figure for"_cons" in this regression?
